No. 11 PLANTS OF CALIFORNIA. BY T. S. BRANDEGEE. - Isomeris arborea Nutt. The type locality of this capparid is San Diego. The original description of its fruit, ‘‘capsule an inch or more long 2nd three-fourths of an inch broad,’’ is very nearly the description of an orbicular capsule. Some of the Desert forms have capsules 7 cm. long including the stipe, and 1 em. wide, and are long-attenuate at each end. The form of the Capsule from the type locality is nearly that of 7. g/lodosa. Fagonia Californica Benth. ‘The form that grows in the foot- hills of the western side of the Colorado Desert is frutescent, erect, and the angles of the stems are scabrous, often as much so as those of F. aspera from Chili. On the hills of the Desert, east of the Cuyamaca Mountains, grows a form so distinct that it seems almost another species, but it probably can be referred to the variety Barclayana; it is prostrate on barren ground, the stems are slightly angled and not frutescent, the leaves and flowers are larger than those of other forms, and the whole plant is thickly beset with amber-colored glands. My specimens from Magda- lena Bay, the type locality, have broader leaflets than the Cali- fornia mountain specimens, the stems are hardly frutescent at base and are not scabrous. At San Jose del Cabo the plants are pubescent, and in the adjaceut mountains the form is glabrous, the leaflets are very narrow and the stipules long and slender. nothera cardiophylla Torr. The “Botany of California’’ ives as the habitat of this species: ‘‘ Near the Colorado River and eastward in Arizona.’’ It grows in the cafions of Carriso and Split Mountains of the Colorado Desert. IsSUED SEPTEMBER 15, 1906. 228 Plants of Caltfornia. [ZOE Nemacaulis Nuttallii Benth. This littoral plant is common along the seashore near San Diego. It also grows abundantly on a sand-dune of the Colorado Desert near Carriso Creek. The two forms named by Nuttall WV. denudata and N. foliosa, are well marked at Ocean Beach, San Diego. Peucephyllum Schottit Gray. ‘This bush has been found north of San Diego County and in northern Lower California, but has not been reported from the intermediate region. I collected it in the cafions af Carriso Mountains, Colorado Desert. Malperia tenuis Watson. On preceeding pages this species was noted as growing near the boundary line about Signal Mountain. It grows also about Split and Carriso Mountains, many miles north of the Mexican boundary line. Krynitzkia barbigera Gray, var. inops. Stems weak, flexuous, with upwardly appressed pubescence; leaves broadly linear; inflorescence congested into glomerules; calyx-lobes much elon- gated at maturity, often more than 1 cm. long, densely bearded below the middle; fully mature nutlets elongated, obclavate, with rather large and sharp-pointed muriculations, the groove open from apex to the dilated base. The type was collected on the Mojave Desert, June, 1884; other specimens not so fully mature are from Inyo, April 16, 1891; San Felipe, April 25, 1899; Keeler, April 14, 1891, and the Needles, Arizona; Dr. E. F. Clark. All in the Brandegee Herbarium. Allium praecox. A peninsulare Jones, Cont. Bot. x. 22, not Lemmon. Five dm. high and less from a bulb 3-4 cm. below the surface of the ground: leaves 2-4 from near the base of the stem, 2 dm. long or less, 4 mm. wide or less: spathe splitting usually into two acuminate segments 2.5 cm. long: umbels 10-20 flowered; pedicels 2-3 cm. long: perianth segments equal in length, 5 mm. long, ovate-acuminate, the inner ones narrower!, nearly white, with purple midnerve becoming dull purple: sta- mens shorter than the perianth, gradually widened to the base; anthers purple: style nearly as long as the filaments, stigma not lobed; capsule crestless: bulb coatings with narrow, linear, hori- zontally contorted reticulations. VOL. 5] Plants of California. 229 This species has been referred to A. unifolium, A. campanula- tum, A, serratum and A. peninsulare by different botanists. A. peninsulare Lemmon, is a plant common in the foothills distant from the coast, rose-pink in color and appears to be a luxuriant form of A. serratum. A. precox is common about San Diego, on northern slopes of cafions, especially near the coast, and is a conspicuous part of the early flora of February. It has been distributed in collections from Ensenada; of Cleveland, from San Diego; El Cajon, San Diego County; S. B. Parish, San Bernardino, No. 4667; A. W. Anthony, 187; Santa Cruz Island, T. S. Brandegee: C. F. Baker, 3391. Dr. Watson’s description of Al/ium hyalinum, Proc. Am. Acad., xxiv. 87, not 4. hyalinum Curran, Bull. Cal. Acad. i. 155, seems to have been drawn from the Santa Cruz Island specimens. Salvia Greatai.

This species has characters both of § Echinosphace and § Pycnos- phace, but is very unlike S. carduacea and S. Columbarie of these sections. It was collected by H. M. Halland L. A. Greata in Cafion Springs wash, about four miles northeast of Dos Palmas, Riverside County, California. No. 5848, H. M. Tetracoccus Hallii.

The genus 7e/racoccus has hitherto consisted of a single species, based on specimens collected by Dr. Parry and C. R. Orcutt, near Santo Tomas, northern Lower California. Since then it has been collected by D. Cleveland, eight miles north of Table Mountain, near the U.S. boundary line, and by C. R. Orcutt, near Temecula and the line of Riverside County, California. ‘The new species is very distinct from the criginal one. rgithamnia Californica. - Annual, moncecious, glabrous throughout, erect, branching, 15 cm. high: leaves ovate-acumin- ate, attenuate at base into a petiole 5-7 mm. long, serrate, 2-3 em. long, 10-12 mm. wide: staminate flowers 2-4 in short axil- lary racemes about as long as the petioles, on pedicels I mm. long; bracts linear, white-margined; sepals linear-lanceolate; petals ovate, acuminate, 2.5 mm. long; glands acuminate, I mm. long: stamens in two verticels from the column: pistillate flower on a pedicel 1 mm. long: sepals 4~5 mm. long, linear-lanceolate, white-margined, glandular-denticulate: petals acuminate; den- ticulate; capsule 4 mm. wide; styles united near the base and deeply bifid, not dilated above; seed apiculate, rugose-reticulated.

Purpus, made dur- ing the years 1906 and i907, at Zacuapan, Vera Cruz, Esperanza and Boca del Monte, Puebla, and at San Luis Tultitlanpa, South- western Puebla, near the State of Oaxaca. The region about Zacuapan and Mirador has been visited by Galeotti, Sartorius, Liebman and other collectors, consequently the large collections of Dr. Purpus from this part of Mexico contain few undescribed’ . forms. Most of the following species came from the unexplored region between Puebla and Oaxaca.

The genus Fendlerella is not very distinct from Whzpplea in -floral-and fruiting characters, but differs very much in habit and leaves. The leaves of F. Utahensis, like those of 7. Mexicana, break away, leaving’a base silky-hairy in the axils; this char- acter is especially evident with F. Mexicana, for the leaves are soon deciduous, the nodes are only 3-4 mm. apart, and the long, white silky-hairs give a gray appearance to the otherwise naked branchlets. The base of some stems is 1 cm. thick. Collected on rocky slopes of Cerro de Baxtle, Puebla. No. 2588. Rhynchosia prostrata.

CRYPSIS ACULEATA Ait. Alkali soil near Norman, Glen Co., May, 1898, /. Burtt Davy; near Stockton, Oct. 2, 1907, Mrs, Brandegee, determined by Prof. A.S. Hitchcock. Mrs. Brande- gee reports it as very abundant over considerable areas, especially on low lands which had been overflowed. Mr. Davy’s specimens are only 1 to 2 cm. ‘broad and high; those gathered by Mrs. Brandegee are larger, a single plant often forming a dense mat 3 dm. or more in diameter. This large size is apparently attained only by summer and autumnal plants. SISYRINCHIUM ELMERI Greene.

Phacelia namatoides Gray, Proc. Amer. Acad. x. 317 (1875). In the original description Dr. Kellogg describes the second internode as “enlarging above, ancipitally expanded at the base of the leaves or compressed, and with the branches decurrent winged.” This is an abnormality, as is plainly evident from a specimen, presumably of the type collection, preserved in the Brandegee Herbarium. VOL. 5] Studies on Californian Plants. 265 PHACELIA HUMILIS T.&G. This species is described as being diffusely branched from the base and with the leaves all alternate. Specimens from Lassen Co., Baker GS’ Nutting, are diffusely branched but have the lower leaves opposite. Specimens from Marlette Peak, Washoe Co., Nevada, Hall & Chandler, No. 4577, vary from the type form in being strict, nearly simple- stemmed, and in their opposite lower leaves. This form comes also from Lassen Creek, Modoc Co., California, M/s. Austin. But in all its forms P. humilis may be distinguished from P. race- mosa and P. Pringlet, the only other species with opposite leaves, by the hirsute pubescence, larger flowers, and exserted stamens. ErRIODICTYON LospBii (Gray) Greene, Bull. Calif. Acad. i. 202 (1885). This species ranges farther north and east than has been generally supposed, and is to be expected in the arid Transi- tion Zone almost anywhere in the northern Sierra Nevada. It has been collected at the south base of Mt. Shasta, at Sardine Lake, Sierra Co., in the lava beds of Modoc Co., and in Nevada (Washoe Co.). ‘The leaves are of two sorts, the lower and the fascicled ones being duJl green and glandular above, loosely tomentose beneath, strongly revolute, at times so much so as to seem almost cylindric, while the upper ones are white-tomentose on both sides, plane, and 4 to 12 mm. broad.

Fl. ), or as.‘ silky-pubescent ’’ (Gray, Bot. Calif.), but there is consider- able variation in this character. Plants from Mt. Tallac (Hal/ Chandler, No. 4612) exhibit two forms, the one with silky- together among rocks in the Hudsonian Zone. Pyramid Peak - specimens (Hall & Chandler, No. 4734) have mostly glabrous achenes, but in a few cases the whole surface of the achene is covered with a villous me actu which approaches the silky character of the typical form. e following collections have glabrous achenes: near Baecne tie Calif., Brandegee,; Washoe Co., Nevada, O. F. Hezzer; Steins Mts., Ore., Cusick, of the Rocky Mt. collections at hand, as well asa majority of the Californian collections, exhibit only ‘pubescent achene SENECIO TRIANGULARIS Hook. Acco ording to Prof. Greene, all of the Californian forms should be received into his S. ¢rigono- phyllus. ‘This species is supposed to have more finely serrate and Rocky Mt. form is frequently compound, — in ours a is some- times simple; and the involucre measures 8 to 10 . high, as against 6 to 8 mm. in Californian plants. If there is isa a difference in leaf-texture, I am unable to detect it in dried specimens. But according to field observations, this character varies considerably in a given locality, being largely dependent upon degree of ex- posure. The form which Professor Greene probably had in hand while describing 5S. trigonophyllus is plentiful in the Lake Tahoe district, in shaded places, but since it ae by all its characters into typical S. triangularis, which is also common in ee soir Shane Sierra, it cannot be specifically senate, either morphologic or geographic grounds. sa DIOLUS HEpypnots All.
